Urban green belt water collecting layer structure

Abstract

The invention discloses an urban green belt water collecting layer structure, and relates to the technical field of urban green belt construction. The problem that an existing water collecting layer structure is prone to being damaged by plant roots and then fails is mainly solved. According to the main structure, the urban green belt water collecting layer structure comprises a water passing channel composed of a siphon water tank, macromolecule protection drainage special-shaped pieces are arranged on the two sides of the water passing channel, splicing seam shielding plates are arranged on the lower part of the outer walls of the two sides of the siphon water tank, and a water inlet is further formed between each splicing seam shielding plate and the edge of the lower part of the siphon water tank. According to the urban green belt water collecting layer structure, the splicing seam shielding plates are arranged to cover splicing seams between the macromolecule protection drainage special-shaped pieces and the siphon water tank, direct damage of the plant roots to the splicing seams can be greatly reduced, and then the service life of the water collecting layer is prolonged.

Description

technical field [0001] The invention relates to the technical field of urban green belt construction, in particular to a water collection layer structure of an urban green belt. Background technique [0002] At present, with the advancement of the country's urban construction, more and more urban construction is also developing step by step. However, with the frequent occurrence of extreme weather nowadays, many urban areas have problems of waterlogging, sea view in the city, and poor drainage. Of course, there are also many urban areas that suffer from drought, water scarcity, and water scarcity. For this reason, in 2013, "Technical Guidelines for Sponge City Construction - Construction of Rainwater System for Low-Impact Development (Trial)" put forward the concept of "sponge city"-that is, to make full use of the role of green belts in cities, The structure of drainage and water collection layer is set under the layer, so that the city can be like a sponge, which has goo...

Problems solved by technology

[0004] However, since the geotextile cannot stop the downward growth of the plant root system - the plant root system will pass through the geotextile, the splicing seam of the current polymer protective drainage profile and the siphon drainage groove will be directly exposed to the growth path of the plant root system

As a result, the downward-growing plant roots will pass directly through the seam of the polymer protective drainage profile and the siphon drainage groove, destroying the entire catchment layer structure and causing the catchment layer to fail
